Hetucakra
''Hetucakra'' or ''Wheel of Reasons'' is a Sanskrit text on logic written by Dignaga (c 480–540 CE). It concerns the application of his 'three modes’ ( trairūpya), conditions or aspects of the middle term called ''hetu'' ("reason" for a conclusion) or ''linga'' ("mark", "sign" of a sound argument) in a valid inference within the Indian logico-epistemic tradition, sometimes referred to as Buddhist logic. Anacker's assessment Anacker (2005: p. 34), in introducing his English rendering of the "Method for Argumentation (Vāda-vidhi)" of Vasubandhu (fl. 4th century)—a text composed in Sanskrit which is now only extant in a reconstructed composite extracted from Tibetan works, collated by Frauwallner (1957)—holds that: Vasubandhu's criteria for a valid inference-schema are concise and precise, and there is nothing essential omitted. Dignāga's 'wheel of justifications' (''hetu-cakra''), sometimes held to be the first complete Indian formulation of what constitutes the v ...

Trairūpya
''Trairūpya (''Sanskrit; English: "the triple-character of inferential sign") is a conceptual tool of Buddhist logic. The Trairūpya, ‘three conditions’, is oft accredited to Dignaga (c. 480-540 CE) though is now understood to have originated with his teacher Vasubandhu (fl. 4th century) in the ''Vāda-vidhi'', post-reconstruction of this work by Frauwallner (1957). Trairūpya is a logical argument that contains three constituents which a logical ‘sign’ or ‘mark’ (linga) must fulfill to be 'valid source of knowledge' (pramana): #It should be present in the case or object under consideration, the ‘subject-locus' (pakṣa) #It should be present in a ‘similar case’ or a homologue (sapakṣa) #It should not be present in any ‘dissimilar case’ or heterologue (vipakṣa) When a ‘sign’ or ‘mark’ (linga) is identified, there are three possibilities: the sign may be present in all, some, or none of the sapakṣas. Likewise, the sign may be present in all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Logic
The development of Indian logic dates back to the ''anviksiki'' of Medhatithi Gautama (c. 6th century BCE); the Sanskrit grammar rules of Pāṇini (c. 5th century BCE); the Vaisheshika school's analysis of atomism (c. 6th century BCE to 2nd century BCE); the analysis of inference by Gotama (c. 6th century BC to 2nd century CE), founder of the Nyaya school of Hindu philosophy; and the tetralemma of Nagarjuna (c. 2nd century CE). Indian logic stands as one of the three original traditions of logic, alongside the Greek and the Chinese logic. The Indian tradition continued to develop through early to modern times, in the form of the Navya-Nyāya school of logic. Origins The Nasadiya Sukta of the ''Rigveda'' ( RV 10.129) contains ontological speculation in terms of various logical divisions that were later recast formally as the four circles of '' catuskoti'': "A", "not A", "A and 'not A'", and "not A and not not A". Medhatithi Gautama (c. 6th century BCE) founded the ''anviksiki'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extant Literature
Ancient literature comprises religious and scientific documents, tales, poetry and plays, royal edicts and declarations, and other forms of writing that were recorded on a variety of media, including stone, stone tablets, papyri, palm leaves, and metal. Before the spread of writing, oral literature did not always survive well, but some texts and fragments have persisted. One can conclude that an unknown number of written works too have likely not survived the ravages of time and are therefore lost. Incomplete list of ancient texts Bronze Age Early Bronze Age: 3rd millennium BC (approximate dates shown). The earliest written literature dates from about 2600 BC (classical Sumerian). The earliest literary author known by name is Enheduanna, a Sumerian priestess and public figure dating to ca. 24th century BC. Certain literary texts are difficult to date, such as the ''Egyptian Book of the Dead'', which was recorded in the ''Papyrus of Ani'' around 1240 BC, but other versions of ...

History Of Logic
The history of logic deals with the study of the development of the science of valid inference (logic). Formal logics developed in ancient times in Indian logic, India, Logic in China, China, and Greek philosophy, Greece. Greek methods, particularly Aristotelian logic (or term logic) as found in the ''Organon'', found wide application and acceptance in Western science and mathematics for millennia.Boehner p. xiv The Stoicism, Stoics, especially Chrysippus, began the development of predicate logic. Christian philosophy, Christian and Logic in Islamic philosophy, Islamic philosophers such as Boethius (died 524), Ibn Sina (Avicenna, died 1037) and William of Ockham (died 1347) further developed Plato's logic in the Medieval philosophy#High Middle Ages, Middle Ages, reaching a high point in the mid-fourteenth century, with Jean Buridan. The period between the fourteenth century and the beginning of the nineteenth century saw largely decline and neglect, and at least one historian of l ...

Buddhist Logic
Buddhist logico-epistemology is a term used in Western scholarship for '' pramāṇa-vāda'' (doctrine of proof) and ''Hetu-vidya'' (science of causes). Pramāṇa-vāda is an epistemological study of the nature of knowledge; Hetu-vidya is a system of logic. These models developed in India during the 5th through 7th centuries. The early Buddhist texts show that the historical Buddha was familiar with certain rules of reasoning used for debating purposes and made use of these against his opponents. He also seems to have held certain ideas about epistemology and reasoning, though he did not put forth a logico-epistemological system. The structure of debating rules and processes can be seen in the early Theravada text the Kathāvatthu. The first Buddhist thinker to discuss logical and epistemic issues systematically was Vasubandhu in his ''Vāda-vidhi'' ("A Method for Argumentation"), who was influenced by the Hindu work on reasoning, the '' Nyāya-sūtra''.Anacker, Stefan (2005, r ...

Vasubandhu
Vasubandhu (; Tibetan: དབྱིག་གཉེན་ ; floruit, fl. 4th to 5th century CE) was an influential bhikkhu, Buddhist monk and scholar from ''Puruṣapura'' in ancient India, modern day Peshawar, Pakistan. He was a philosopher who wrote commentary on the Abhidharma, from the perspectives of the Sarvastivada and Sautrāntika schools. After his conversion to Mahayana, Mahayana Buddhism, along with his half-brother, Asanga, he was also one of the main founders of the Yogacara school. Vasubandhu's ''Abhidharmakośakārikā'' ("Commentary on the Treasury of the Abhidharma") is widely used in Tibetan and East Asian Buddhism, as the major source for non-Mahayana Abhidharma philosophy. His philosophical verse works set forth the standard for the Indian Yogacara metaphysics of "appearance only" (''vijñapti-mātra''), which has been described as a form of "epistemological idealism", Phenomenology (philosophy), phenomenology and close to Immanuel Kant's transcendental ideali ...

Chakra
Chakras (, ; sa , text=चक्र , translit=cakra , translit-std=IAST , lit=wheel, circle; pi, cakka) are various focal points used in a variety of ancient meditation practices, collectively denominated as Tantra, or the esoteric or inner traditions of Hinduism.Chakra: Religion Encyclopaedia Britannica The concept of the chakra arose in the early traditions of Hinduism. Beliefs differ between the Indian religions, with many Buddhist texts consistently mentioning five chakras, while Hindu sources reference six or seven. Early Sanskrit texts speak of them both as meditative visualizations combining flowers and mantras and as physical entit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nyāya Sūtras
The ''Nyāya Sūtras'' is an ancient Indian Sanskrit text composed by , and the foundational text of the Nyaya school of Hindu philosophy. The date when the text was composed, and the biography of its author is unknown, but variously estimated between 6th-century BCE and 2nd-century CE.Jeaneane Fowler (2002), Perspectives of Reality: An Introduction to the Philosophy of Hinduism, Sussex Academic Press, , page 129 The text may have been composed by more than one author, over a period of time. The text consists of five books, with two chapters in each book, with a cumulative total of 528 aphoristic sutras, about rules of reason, logic, epistemology and metaphysics.Jeaneane Fowler (2002), Perspectives of Reality: An Introduction to the Philosophy of Hinduism, Sussex Academic Press, , pages 127–136 The Nyāya Sūtras is a Hindu text, notable for focusing on knowledge and logic, and making no mention of Vedic rituals.

Indian Philosophy
Indian philosophy refers to philosophical traditions of the Indian subcontinent. A traditional Hindu classification divides āstika and nāstika schools of philosophy, depending on one of three alternate criteria: whether it believes the Vedas as a valid source of knowledge; whether the school believes in the premises of Brahman and Atman; and whether the school believes in afterlife and Devas. There are six major schools of Vedic philosophy— Nyaya, Vaisheshika, Samkhya, Yoga, Mīmāṃsā and Vedanta, and five major heterodox (sramanic) schools—Jain, Buddhist, Ajivika, Ajñana, and Charvaka. However, there are other methods of classification; Vidyaranya for instance identifies sixteen schools of Indian philosophy by including those that belong to the Śaiva and Raseśvara traditions.Cowell and Gough, p. xii.Nicholson, pp. 158-162. The main schools of Indian philosophy were formalised and recognised chiefly between 500 BCE and the late centuries of the Common Era. Com ...

Madhyamaka
Mādhyamaka ("middle way" or "centrism"; ; Tibetan: དབུ་མ་པ ; ''dbu ma pa''), otherwise known as Śūnyavāda ("the emptiness doctrine") and Niḥsvabhāvavāda ("the no ''svabhāva'' doctrine"), refers to a tradition of Buddhist philosophy and practice founded by the Indian Buddhist monk and philosopher Nāgārjuna (c. 150 – c. 250 CE).Wynne, Alexander (2015) ''Early Buddhist Teaching as Proto-śūnyavāda.'' Journal of the Oxford Centre for Buddhist Studies, 6. pp. 213-241. The foundational text of the Mādhyamaka tradition is Nāgārjuna's ''Mūlamadhyamakakārikā'' ("Root Verses on the Middle Way"). More broadly, Mādhyamaka also refers to the ultimate nature of phenomena as well as the non-conceptual realization of ultimate reality that is experienced in meditation. Mādhyamaka thought had a major influence on the subsequent development of the Mahāyāna Buddhist tradition. It is the dominant interpretation of Buddhist philosophy in Tibetan Buddhism and ...
